fuck man, i forgot about Jackmayoffer. Dude was hella cool. kind of a dick sometimes, but he knew his shit.
Anthem is right. there used to be some gods around these parts that pretty much wrote the books on clandestine commercial grow methods, and a lot of them killed it in wool. Anthem is also correct about wool being probably the most advanced grow media simply because of how flexible it is and what you can do with it. You're on track to killing this run so far, and if you set up your equipment right and get that environment dialed, you will be blown away by how much faster the growth rates are vs just about any other method. The only other method that might rival it in speed of growth is RDWC in an undercurrent configuration. It's really a method for those looking to push their skills to the max. The nice thing is once you figure out your scheduling and all that, it's pretty simple to use. You just have to watch a ton of data points and have automation in place otherwise shit will go sideways quickly.
I trust you got this though, you saw how quickly your plants turned around by getting VPD more into the right range. You'll need to get a light meter too otherwise you're going to do what I did... Twice... and introduce calcium deficiencies and foxtailing come flower. Wish i had bit the bullet and bought an apogee at the beginning of this run but I didn't won't make that mistake again during another production run.
